1.01 {240} \ approximate 10.8926 is calculated by a calculator.Substituting r = 0.01 and n = 240 into the above formula, we can get:\end{align*}
This means that after 240 trading days, the overall increase multiple is about 115.8887 times, which is converted into the form of increase percentage, and the increase is (115.8887-1)×100\% = 11488.87\%.Therefore, the daily increase is 2%, and after 240 trading days, the increase is about 11,488.87 \%.&=1.01^{240}
\end{align*}Step 1: Review the formula of compound interest final value.Therefore, according to the daily increase of 1\%, the increase is about 989.26\% after 240 trading days.
